9340FM

Specialty Logic Overview

The National Semiconductor 9340FM is a 4-bit Arithmetic Logic Unit (ALU) IC housed in a 24-pin CFP package. It operates with a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -55°C to 125°C. The component is designed for surface-mount mounting and functions as a specialty logic device within digital systems.

Specialty Logic Feature Summary

• Performs arithmetic and logical operations on 4-bit data words
• Supports wide industrial temperature operation from -55°C to 125°C
• Compatible with standard 5V logic supply voltages

Specialty Logic Applications

• Digital signal processing units requiring 4-bit calculation capabilities
• Industrial control systems operating in extreme temperature environments
• Embedded logic modules in specialized computing hardware

Specialty Logic Procurement Notes

Verify the specific manufacturer source, as National Semiconductor assets are now managed by Texas Instruments. Confirm the exact package type and pinout compatibility with your PCB design. Ensure the component meets the required voltage and temperature specifications for your target application environment before procurement.

Specialty Logic Selection Notes

Select this component when a dedicated 4-bit ALU is required for logic or arithmetic tasks. Consider the 24-pin CFP package constraints for board layout. Verify that the 5V logic level compatibility matches your system's interface requirements and that the wide temperature range suits the operational conditions.

Specialty Logic Part Context

This part belongs to the National Semiconductor specialty logic family, specifically designed for arithmetic and logical processing. As a legacy component, it represents older TTL-compatible logic standards. Availability may be limited due to the company's acquisition by Texas Instruments, often requiring sourcing from distributors holding legacy inventory.

Specialty Logic Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult Texas Instruments resources for potential modern equivalents or cross-reference with other specialty logic manufacturers for compatible 4-bit ALU solutions.
